To lall lwhom it may concm:

Be it known that I, WILLxAn .losnrn KING, a citizen of the UrltmlStates, residing at Waterifalley, lin the county of Yalobnsha and Stateof Mississippi, have inv'vented new and useful Improvements in CouplingDevices, of which the following is a speciticatinn.

This inventin is a coupling device inthe form of a -donhle hook adaptedto be used fur .mondingy or cminecting the ends of chains, or forattaching the chain tn an object, and the particular object of theinventinn ia to form a hook which will not become nef-iden tallyunhooked. l v

The invention is illustmted in the accompanying drawings, in whichFigure l is a side View showing the luxik connecting tho Vendsutcliains. Fig. 2 is a perspective View of the devil-(,- lookinginto ortoward the angle between th hnoka. Fig. 8 is an end viowof the tlvvice.

.Rofurring specifically to the? drawings, 5 indicates a sltraight shankhaving at one end a honk and at the nppnsitn end. anoppositcly-msentedh0ok 7, which extends imm tmA shank in n planesubstantially' :it n right;
